Milly is selling Girl Scout cookies. She sells 8 boxes every 3 days. How many days will it take her to sell 56 boxes? (1 point)

Answer 1

To find the number of days it will take Milly to sell 56 boxes, we need to divide the total number of boxes by the number of boxes she sells in a given time period.

First, we divide 56 boxes by 8 boxes to find out how many groups of 8 boxes she sells: 56 boxes / 8 boxes/group = 7 groups

Since Milly sells 8 boxes every 3 days, we multiply the number of groups by the number of days it takes to sell 8 boxes: 7 groups * 3 days/group = <<7*3=21>>21 days.

Therefore, it will take Milly 21 days to sell 56 boxes of cookies. Answer: \boxed{21}.
